• Add choice for an alternate method, that will result in a flat render and appear like the first screenshot.
• Make the mode pixel depth variable, for user controlled lag/beauty.
• Add comment lines to the script for better accessibility.

• Support for animated autotiles.
• Support for map priority (tiles appearing over the character).
• RM2k-like airship script with Mode07.
• Redefine the entire method. This will allow:
• FF6-style airship script with map rotation.
• Support for map looping.
• Less lag.

Mode07 on the Map!
Includes:
    Mode07 v0.6
    Overworld Sprite Resize
  Written by mewsterus

Special Thanks:
  Fanha Giang (for a reverse engineered Tilemap class)
--------------------------------------------------------------------------------
Instructions:
--------------------------------------------------------------------------------
To install, just insert this in a descriptive code slot right above Main.
 This is different than previous instructions; please read the next paragraph.

To activate Mode07, add [#XX] to the map's name, replacing XX with the
 percentage of Mode07 to apply.  Greater numbers will result in a more slanted
 world.
 
To activate overworld sprite resize, add [OV] to the map's name.  This will make
 character sprites smaller on that map.

For the purposes of location scripts, these identifiers will not appear.


Examples:

"Overworld[#40]" will result in a slant identical to the second screenshot.
"Underworld[OV]" will resize only the player character to a small size, as if
                 seen from high above.
"Atthelevelworld[OV][#12]" will result in the player being resized, and a modest
                           slant of 12%
"JustPlainWorld" will result in the same old map you've always seen.

To add a sky, simply use the panorama with the tileset.  Also, events will not
 be drawn flat with the map.  Any vertical objects such as trees should be put
 in events and displayed that way. (this can also be used to display objects
 in front of the character, in absence of working priorities)

You can also add a sky by adding a fog.  If you add this, you can make it look
 like the first screenshot.

A note on the $strip_size variable; the default value is 8, however there is
 extremely minimal, almost nonexistant lag with 16. The screen is extremely
 smooth with 4, or even 2. If you're having major problems with lag, you may
 need to use 32, but it won't look too pretty.
